OtoShut

OtoShut is a small-sized and portable piece of software that integrates just a few simple options for scheduling a power management function for the computer, such as shutdown.
The tool's features are easy enough to be figured out even by users with little or no experience in computer software.

Portability benefits

Since there is no installation involved, you can drop the program files in any directory on the hard disk and just click the executable to run.
There is also the option to save OtoShut to a USB flash disk or similar storage unit, in order to run it on any workstation with minimum effort, as long as it has .NET Framework installed.
What's more, the app does not add new entries to the Windows registry or Start menu, leaving no traces behind after its removal.

Simple and straightforward interface

As far as the GUI is concerned, the main app window is very small and shows all options, meaning that there are no other functions available, aside from the ones shown here.
So, all you have to do is specify an exact time and date (anything from the calendar) and select the power option between turn off, stand by, hibernate, restart, log off, and lock.
The tool can be minimized to the taskbar to become non-intrusive. It uses low CPU and RAM, so it does not affect the PC's overall performance. No error dialogs popped up during our evaluation, and OtoShut did not hang or crash.

Conclusion

It may not be feature-rich but OtoShut delivers a simple solution to scheduling the computer to shut down, restart or another power option, and it can be used by anyone with ease.
